Definition
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.

Formation
Pantellerite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

More about Pantellerite and Ganister
Here you can know more about Pantellerite and Ganister. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pantellerite and Ganister consists of mineral content and compound content. The mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite and mineral content of Ganister includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Pantellerite vs Ganister, the texture, color and appearance plays an important role in determining the type of rock. Pantellerite is available in dark greenish - grey colors whereas, Ganister is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Pantellerite is Layered and Foliated and that of Ganister is Rough. Properties of rock is another aspect for Pantellerite vs Ganister. Hardness of Pantellerite and Ganister is 6-7. The types of Pantellerite are Pantelleritic Ignimbrite whereas types of Ganister are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface.
